The latter proved to be a costly, ninth-inning error, allowing the go-ahead run to score in the finale of a homestand with Mississippi. Dayan Viciedo's miscue allowed Travis Jones to score the go-ahead run with two outs.

Just two batters earlier, Jones seemed to be out on a double play at second, but the umpiring crew ruled Barons' shortstop C.J. Lang missed the bag on the front end of the play.

The bigger argument came in the sixth on a one-hop line drive to second baseman C.J. Retherford, who converted the play into a 4-6-3 double play. However, an inadvertent ruling of an infield fly negated the force out at second. Barons manager Ever Maggallanes argued the call for a dozen minutes, to no avail.

According to Rule 2.00, however, the infield fly was not in effect because no baserunner occupied second base.

The loss dropped the Barons to 33-16. The club heads into the final game of May at 1 p.m. in Huntsville on Sunday with a shot at 20 wins - which would tie for the most in a month set in August 2005.
